SUPPORT FOR FLASH-LIGHT LAMPS OR THE LIKE.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed July 30, 1906. Serial No. 328,367.

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a support for flash-light lamps or the likewhich extends between the ceiling and the floor and con-- sists of twoor more parts that are joined together telescopically or by sliding inor on one another or by being linked to each other, so that they may beadjusted and fixed relatively to each other in order that the supportmay be held firmly between the ceiling and floor in rooms of differentheight.

In the drawing Figure 1 is a side view of a flash-light support composedof a plurality of telescopically arranged tubes. In Fig. 2 the side viewof another support is shown, composed of several rods suitably linkedtogether. Fig. 3 is a sectional side elevation of a flash-light supportwith a central tube and two rods as end parts. The support shown in sideview in Fig. 4 comprises but two parts slidably arranged within eachother, while in Fig. 5 two rods are adjustably arranged against eachother. Fig. 6 is a top view of the foldable cross-arms provided withprotecting pads. Figs. 7, 8 and 9 are detail views of the clamp wherebythe tubes are secured in their relative position.

In the form shown in Fig. 1 two tubes 11 which I call the central tubesare fixed together, as by fixing one into the other, and into each slidetelescopically a number of other tubes 12, 13, 14 which may be fixed inposition for use in any suitable manner. The topmost tube 14 carriescross arms 7 (Fig. 6) which may be made to fold together in any suitablemanner and are provided with rubber pads or the like 8 to prevent themfrom damaging the ceiling. Mounted on these arms. are pulleys over whichpasses the cord whereto the lamp container 9 is attached, this cordbeing held by a clamp 10 of any known kind.

The lowest tube 14 carries a point or a button with a roughened surfaceto prevent the support from sliding on the floor.

In the form shown in Fig. 2, the support consists of two parts 16, 17pivoted together and each connected by a link 18 with a nut 20 in whichworks a screw 19. The end of this screw is connected with the pivotjoining the two parts 16, 17 so that by adjusting the screw these partsmay be fixed to make different angles with each other and held firmlybetween the ceiling and the floor.

In the form shown in Fig. 3 the two parts 11, one terminating in arubber pad 8 and the other in a point 15, slide in a tube 21 whichincloses a spring 22 whereby the adjustment of the support betweenceiling and floor is automatically ellected. I11 Figs. 4 and 5 are shownsupports consistii'ig of two parts, sliding one in the other and one onthe other, respectively, and held in position by a set screw 19. In thiscase also one part carries a rubber pad 8 and the other a point or abutton 15.

The parts that slide in or on each other can be fixed in the requiredrelative position in any suitable manner. For the telescopicmodification (Fig. 1) the following fixing device is suitable.

On the slitted end of the tube a ring 1 having wedge-shaped projections2 is permanently fixed or movably attached (Figs. 79). A bow 3 is fixedon the said projections and in this bow a piece 4 is guided which hasoblique surfaces bearing on the like surfaces of the projections 2. Bymeans of a screw 5 the piece 4 can be pressed so that its obliquesurfaces slide down the like surfaces of the projections, thusdiminishing the diameter of the ring 1 and that of the end of the tube,such as 11, to clamp the latter against the tube that slides in it, suchas 12. The bow 3 may itself be the nut in which the screw 5 works, or itmay carry a separate nut 6 for this purpose.

The ring 1 can either be fixed to the end of the tube or it may bedetachable and adapted to be placed on the end as required, beingprovided for this purpose with pins 10 (Fig. 9) which enga e in openingsor depres- 1 and 2 or connected with the support at any other pointthereof. 1

What I claim as my invention and desire to secure by Letters Patent is:

1. In an extensible support for flash-light lamps, a floor-part, aceiling-part, means to keep the outer ends of the said parts at asuitable distance with respect to each other, and foldable cross-arms onthe top of the ceiling part, substantially as described.

2. In an extensible support for flash-light lamps, two parts, adjustablethe one with respect to the other and bearing respectively against theceiling and the floor, two central tubes, each part connected with oneof the said central tubes by a number of tubes telescopically slidinginto each other and into oneof the said central tubes, a slitted end toeach tube, wedge-shaped projections mounted on the said slitted end, abow attached to said projections, and a piece mounted to slide withinsaid bow, having inclined surfaces adapted to slide on said wedge-shapedprojections and force said piece against said projections, as set forth.

3. In an extensible support for flash-light lamps, a ceiling-part and afloor-part, adjustable the one with respect to the other, two centraltubes, each part connected with one of the said central tubes by anumber of tubes telescopically sliding into each other and into one ofsaid central tubes, a slitted end to each tube, a ring fixed to saidslitted end, wedge-shaped projections on said ring, a bow attached tothe said projections, and a piece mounted to slide within the said bow,having inclined surfaces adapted to slide on the said wedge-shapedprojections and force the said piece against the said projections, as

set forth.

4. In an extensible support for flash-light lamps, a ceiling part and afloor part, adjustable the one with respect to the other, two centraltubes, each part connected with one of the said central tubes by anumber of tubes telescopically sliding into each other and into one ofsaid central tubes, a slitted end to each tube, a ring adapted to beplaced in position on the said slitted end, wedgepart, as set forth..,

6. In an extensible support for flash-light lamps, a ceiling part and afloor part, adjustable the one with respect to theother, means to keepthe said two parts in their relative position, cross arms adapted to befolded, mounted on the top of the upper part,

protecting and retaining means arranged upon said cross arms, and meansto prevent slipping, provided upon the bottom-end of the said lowerpart, as set forth.

'7. In an extensible support for flash-light lamps, a ceiling part and afloor part, adjustable the one with respect to the other, means to keepthe said two parts in their relative position, cross arms adapted to befolded, mounted on the top of the upper part, and means for raising theflash-light lamp on the said cross-arms, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
